Abstract

Two types of core-shell structured dendrimer, 2,4-bis-{3,5-bis-[3,5-bis-(3,5-di-tert- butylbenzylthio)benzylthio]benzyloxy}-6,8-dinitroquinazoline (7a) and 2,4-bis-{3,5-bis-[3,5-bis- (3,5-di-tertbutylbenzyloxy)benzyloxy]benzyloxy}-6,8-dinitroquinazoline (7b) as a referential compound were synthesized. These compounds consist of a 6,8-dinitroquinazoline ring as the functional unit and a 3,5-dimercaptobenzyl or a 3,5-dihydroxybenzyl group as the dendritic unit. In order to protect the sulfur atom in dendrimer (7a) from the oxidation reaction, a 3,5-di-tert- butylbenzyl group was designed as the outer-most unit. The synthesized dendrimer containing 3,5-dimercaptobenzyl blocks (7a) is completely novel, and is interesting as a photoelectronic material to examine what kind of influence the d-orbital electron properties give to the whole molecule.
