Nonperipheral tetrakis(dibutylamino)phthalocyanines. New types of 1,8,15,22-tetrakis(substituted)phthalocyanine isomers

Cyclic tetramerization of 3-(dibutylamino)phthalonitrile in refluxing n-pentanol in the presence of magnesium pentanoate afforded the four regioisomer-containing nonperipheral 1,8-/11,15-/18,22-/25-tetrakis-(dibutylamino)phthalocyaninato magnesium complexes with the 1,8,15,22-tetrakis(dibutylamino)phthalocyanine isomer Mg{Pc[α-N(C4H9)2]4-C4} (2). This, in combination with its much superior crystallinity over the remaining three isomers, renders the easy isolation of 2 only through two simple recrystallizations from THF and methanol. Treatment of 2 with trifluoroacetic acid induced the isolation of metal-free 1,8,15,22-tetrakis-(dibutylamino)phthalocyanine, H2{Pc[α-N(C4H9)2]4-C4} (1), which further reacted with M(OAc)2·nH2O (M = Ni, Zn) in refluxing n-pentanol, giving the 1,8,15,22-tetrakis(dibutylamino)phthalocyaninato metal complexes M{Pc[α-N(C4H9)2]4-C4} (M = Ni (3), Zn (4)). The full series of four 1,8,15,22-tetrakis(dibutylamino)phthalocyanine isomeric compounds have been characterized by a series of spectroscopic methods and single-crystal X-ray diffraction analyses. Obviously, the present result provides a simple and effective pathway for the synthesis and isolation of novel 1,8,15,22-tetrakis(dibutylamino)-phthalocyanine isomeric derivatives, providing one step forward toward completing bis(alkyl)amino-incorporated phthalocyanine species.

Water-induced fluorescence quenching of mono- and dicyanoanilines

Photophysical properties of monocyano- (2-, 3-, and 4-cyano) and dicyano- (3,4-, 3,5-, 2,3-, 2,4-, 2,5-, and 2,6-dicyano) anilines are investigated by fluorescence measurements. All the monocyanoanilines are virtually nonfluorescent in water (quantum yield 0.01); however, in nonaqueous solvents (cyclohexane, acetonitrile and ethanol), the fluorescence quantum yield is enhanced substantially. In contrast, dicyanoanilines investigated are highly fluorescent both in aqueous and nonaqueous environments. The photophysical data and MO calculations suggest that conformational changes in the amino group and variation of hydrogen-bonding interactions between the solute and solvent water upon electronic excitation are responsible for the water quenching in the monocyanoanilines.
