The synthesis of triazolephthalocyanines bearing crown ether and aza-crown ether substituents is described. Different substituents have been introduced on the nitrogen atom of the aza-crown moiety to improve the solubility and the intrinsic amphiphilic character of these macrocycles. The crowned tri

## Abstract Thirteen, benzo[__a__]phenoxazinโ€5โ€one derivatives 3aโ€m were synthesized from 4โ€nitrosoaniline hydrochlorides 1aโ€m and ethyl 1,3โ€dihydroxynaphthoate 2 and their fluorescence properties were discussed in terms of the electronic effect of substituents. A coupling reaction was carried out
