PHOTO- AND THERMOCHROMIC SPIRANS. 41. QUANTUM CHEMICAL INVESTIGATIONS OF GEOMETRY AND ELECTRONIC STRUCTURE OF 1',3',3'-TRIMETHYL-1,2-DIPHENYLSPIRO[FURO[3,2-f]CHROMENE-7,2'-INDOLINE] IN THE GROUND AND EXCITED STATES

Abstract

A quantum chemical modeling of the geometry and electron structure of the ground and lower exited states of a spirane class photochromic compound 1',3',3'-trimethyl-1,2-piphenylspiro[furo[3,2-f]chromene-7,2'-indoline] was carried out. On the basis of hte electron excitation localization in the molecule it was proposed that the photoinduced transformation of the colorless spiro-form into a colored merocyanine photoproduct occurs with most likely from its lower singlet, and not the triplet excited state.
