摘要：
Four dibenzo[a,c]phenazine based donor-acceptor tetra branched molecules were synthesized. The optical (including absorption, steady state and time resolved fluorescence) and electrochemical properties of these compounds were investigated. The emitting behavior of these molecules depends on the donor strength of the side-arms. Tuning of optical properties has been performed by varying side-arms. Electron deficient 4-(2-benzothiazolyl)phenyl side-arm compound emit light in the blue region. Weak donor (4-methoxyphenyl substituted) compound shows red shifted emission in green region. With strong donor (thiophene and triphenylamine) substituted compounds exhibits red and orange-red emission respectively.
