Abstract

ONE OF THE BEAUTIFUL ASPECTS OF CHEMISTRY, ESPECIALLY COORDINATION COMPOUNDS IS CHROMO TROPISM PHENOMENON. THERE ARE SEVERAL POTENTIAL APPLICATIONS FOR THIS PHENOMENON SUCH AS USE IN THERMO SENSITIVE, IMAGING, PHOTO SWITCHING, LEWIS ACID–BASE COLOR INDICATOR, SENSOR MATERIAL, AND POLLUTANT SENSORS [1]. CHROMO TROPISM IS THE REVERSIBLE CHANGE IN COLOR OF A SUBSTANCE UNDER DIFFERING PHYSICAL OR CHEMICAL CONDITIONS SUCH AS TEMPERATURE (THERMOCHROMISM) AND SOLVENT (SOLVATOCHROMISM), PH(HALOCHROMISM), ION (IONCHROMISM).A LIMITED NUMBER OF COMPOUNDS SHOW COMBINATION THESE PHENOMENA [2]. HERE IN, A NEW BINUCLEAR MIXED-CHELATE COMPLEX WITH GENERAL FORMULA [CU2(TAE)(DIAMINE)2]X2 WHERE TAE = TETRAACETYLETHANE, DIAMINE = N,NDIPROPYLAMIDETHYLENEDIAMINE, X=CLO4 HAS BEEN SYNTHESIZED AND CHARACTERIZED ON THE BASES OF ELEMENTAL ANALYSIS, SPECTROSCOPIC, CONDUCTANCE MEASUREMENTS AND X-RAY CRYSTAL ANALYSIS (FIG 1). THE COMPLEX SHOWS HALOCHROMISM IN AQUEOUS SOLUTION, SO THAT THE ORIGINAL BLUE COLOR OF THE SOLUTION TURNS TO PURPLE UPON ADDITION OF ABASE (NAOH, 0.1 M). THIS REVERSIBLE PHENOMENON IS AS A RESULT OF PROTONATION AND DEPROTONATION OF AMIDE GROUPS IN AQUEOUS SOLUTION. THE DINUCLEAR COMPLEX WAS ALSO OBSERVED TO EXHIBIT THERMOCHROMISM IN BOTH SOLID STATE AND SOLUTION ALONG WITH IONOCHROMISM AS A RESULT OF HEMILABILITY OF AMIDE GROUP.
