Abstract

Floating layer structure of mesogenic phthalocyanine of A3B-type

“…19 In our previous reports on the structure and physicochemical properties of asymmetric phthalocyanine derivatives of A 3 Btype, it was shown that the number of acceptor substituents (two or four chlorine atoms) introduced to the molecule significantly affects electronic absorption spectra (both in solutions and thin films), energy of boundary orbitals (HOMO/LUMO), values of the dipole moment, and mesomorphic properties of those compounds. 16,18 A difference in photoelectric properties of heterophase systems based on phthalocyanines of this type in combination with fullerene C 60 was also observed. 16 In the present work, we continued our ongoing research and comprehensively examined the floating layer structure formed by asymmetric 1,4,8,11,15,18-hexaoctyloxy-22,23,24,25-tetrachlorophthalocyanine 1.…”

“…These compounds are capable of forming liquid crystalline phases containing a columnar packing of molecules and upon cooling, they ensure a vitrification of thin films preserving the structure of preceding columnar phase. 16,17 In classic photovoltaic cells, the active light absorbing layer is a multicomponent composition, where each of the components is separately responsible for the light absorption, vitrification, electron transfer, and one-dimensional conductivity, viz. the required properties for successful functioning of such devices.…”

Synthesis and Properties of Sulfo and Alkylsulfamoyl Substituted Phthalocyanines and their Copper (II) Complexes Bearing 1-Benzotriazolyl and 4-Cyclohexylphenoxy Groups

“…In this work, we continue investigations concerning synthesis of sulfo-and alkylsulfamoyl derivatives of aryloxy-substituted phthalocyanines [2][3]. We have previously shown that the presence of donor and acceptor substituents imparts the ability for non-mesogenic compounds to show thermotropic mesomorphism [4][5][6][7]. While the introduction of sulfo or alkylsulfamoyl fragments into para-position with respect to the oxygen atom of aryloxy group of mixsubstituted phthalocyanines does not affect the ability of these compounds to exhibit mesomorphism.…”
