摘要：

Five monomacrocyclic (12a - e) and three types of threefold azobenzene-bridged oligomacrocyclic compounds (15, 17, 28, 31) have been synthesized. Due to the cavity-forming chromophores at the periphery of these molecules they represent concave dyes. The watersoluble monocycles 12b - e were photoisomerized and investigated before and after E/Z isomerization with regard to their host properties for small neutral organic guest compounds. The bicyclic azobenzene derivative 31 with triphenylethane spacers exhibits in/out isomerism. The in/out isomer 31 c was separated by HPLC from 31 a and b, which are in equilibrium at room temperature. The tris(2-aminoethyl)amine-capped Schiff bases 15 and 17 form complexes with Cu(CH3CN)4BF4.
