Qhov sib txawv tseem ceeb ntawm supramolecular chemistry thiab molecular chemistry yog tias supramolecular chemistry cuam tshuam nrog kev qaug zog, thim rov qab tsis muaj kev cuam tshuam ntawm cov molecules whereas molecular chemistry cuam tshuam nrog cov cai tswj kev tsim thiab tawg ntawm cov tshuaj sib txuas ntawm molecules.
Chemistry yog ib qho kev kawm dav uas tuaj yeem faib ua ntau yam nyob ntawm qhov kev kawm. Qee qhov chaw ntawm chemistry muaj xws li organic chemistry, inorganic chemistry, Physical chemistry, analytical chemistry, molecular chemistry, supramolecular chemistry, etc.
Dab tsi yog Supramolecular Chemistry?
Supramolecular chemistry yog ceg ntawm chemistry uas cuam tshuam nrog cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov molecules. Muaj peev xwm sib txawv ntawm cov molecules no, xws li intermolecular rog, electrostatic rog, hydrogen bonds, muaj zog covalent bonds, thiab lwm yam. Supramolecular chemistry feem ntau cuam tshuam nrog cov tsis muaj zog, thim rov qab tsis yog covalent bonds. Cov ntawv cog lus zoo li no suav nrog kev sib koom tes hlau, kev siv zog hydrophobic, Van der Waals rog, kev sib cuam tshuam pi-pi, thiab kev sib cuam tshuam electrostatic.
Tsis tas li ntawd, muaj qee cov ntsiab lus tshuaj lom neeg uas tau tham hauv qab supramolecular chemistry. Cov no muaj xws li molecular self-assembly, molecular folding, molecular recognition, dynamic covalent chemistry, thiab lwm yam. Txij li thaum qhov kev kawm no qhia txog tus cwj pwm ntawm cov tsis-covalent kev sib cuam tshuam, nws yog ib qho tseem ceeb heev rau kev nkag siab txog ntau yam kab mob lom neeg uas vam khom cov tshuaj sib cuam tshuam.
Thaum xav txog cov ntsiab lus hauv supramolecular chemistry, ceg tseem ceeb tshaj plaws yog lub rooj sib txoos molecular uas peb tham txog kev tsim kho cov tshuab yam tsis muaj kev taw qhia los ntawm ib qho chaw sab nraud. Hauv lwm lo lus, lub tswv yim no piav qhia yuav ua li cas molecules raug coj los sib sau ua ke los ntawm kev sib cuam tshuam uas tsis yog-covalent.
Daim duab 01: Ib qho piv txwv ntawm Molecular Assembly
Molecular complexation thiab kev lees paub yog lwm qhov chaw tseem ceeb hauv supramolecular chemistry, uas suav nrog kev khi tshwj xeeb ntawm cov qhua molecule rau ib tus tswv tsev molecule complementary, tsim ib lub party- qhua complex.
Molecular Chemistry yog dab tsi?
Molecular chemistry yog ceg ntawm chemistry uas cuam tshuam nrog kev tsim thiab tawg ntawm cov tshuaj sib txuas ntawm cov molecules. Qhov kev kawm no yog nyob rau hauv molecular science; muaj ob yam kev kawm nyob rau hauv molecular science, molecular chemistry thiab molecular physics (nyob rau hauv uas peb tham txog cov cai tswj cov qauv thiab cov khoom ntawm molecules).
Raws li molecular chemistry, cov molecule yog ib qho system ruaj khov (peb hu nws lub xeev khi) uas muaj ob lossis ntau lub atoms (polyatomic). Polyatomic ions raug suav hais tias yog cov khoom siv hluav taws xob thaum lub sij hawm tsis ruaj khov molecule yog siv rau hom reactive heev. e.g. luv luv nuclei, radicals, molecular ions, thiab lwm yam.
Daim duab 02: Ionic Bond Formation
Supramolecular chemistry cuam tshuam nrog kev cuam tshuam ntawm cov molecules whereas molecular chemistry cuam tshuam nrog kev sib txuas hauv cov molecule. Muaj ob hom tshuaj tiv thaiv kab mob uas tuaj yeem nyob hauv ib lub molecule; Covalent daim ntawv cog lus thiab daim ntawv cog lus ionic.
Qhov txawv ntawm Supramolecular Chemistry thiab Molecular Chemistry yog dab tsi?
Supramolecular chemistry thiab molecular chemistry yog ob qhov chaw ntawm chemistry. Qhov sib txawv tseem ceeb ntawm supramolecular chemistry thiab molecular chemistry yog tias supramolecular chemistry cuam tshuam nrog kev qaug zog, thim rov qab tsis yog-covalent kev sib cuam tshuam ntawm cov molecules whereas molecular chemistry cuam tshuam nrog cov cai tswj kev tsim thiab tawg ntawm cov tshuaj bonds ntawm molecules.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm supramolecular chemistry thiab molecular chemistry.
Summary – Supramolecular Chemistry vs Molecular Chemistry
Supramolecular chemistry thiab molecular chemistry yog ob qhov chaw ntawm chemistry. Qhov sib txawv tseem ceeb ntawm supramolecular chemistry thiab molecular chemistry yog tias supramolecular chemistry cuam tshuam nrog kev qaug zog, thim rov qab uas tsis yog-covalent kev sib cuam tshuam ntawm cov molecules whereas molecular chemistry cuam tshuam nrog cov cai tswj kev tsim thiab kev tawg ntawm cov tshuaj sib txuas ntawm cov molecules.
