Novel tetraazachlorin (TAC)-fullerene (C60) conjugates (TAC-C60) and their analogues (TAiBC-C60 and TABC-C60 where TAiBC = tetraazaisobacteriochlorin and TABC = tetraazabacteriochlorin) have been synthesized by condensing 1,2-dicyanofullerene (1) and phthalonitrile derivatives (2) in the presence of nickel chloride in quinoline, and fully characterized using mass spectrometry and 1H and 13C NMR.

sandwich-type complexes based on porphyrins fused with imidazole or pyrazine cycle are synthesized and precisely characterised. The influence of the nature of the appended 5- or 6-membered heterocyclic fragments onto the electronic properties of complexes is revealed by means of UV–vis spectroscopy. It is found, that the annulation of pyrazineheterocycle results in the expansion of the aromatic system of the ligand

The synthesis and photophysical properties of several porphyrin (P)–phthalocyanine (Pc) conjugates (P–Pc; 1–3) are described, in which the phthalocyanines are directly linked to the β‐pyrrolic position of a meso‐tetraphenylporphyrin. Photoinduced energy‐ and electron‐transfer processes were studied through the preparation of H2P–ZnPc, ZnP–ZnPc, and PdP–ZnPc conjugates, and their assembly through metal
Electrochemical and theoretical investigations over triple-quadruple-, quintuple-, and sextuple-decker sandwich-type compounds [(Pc*)Sm][(Pc*)Cdn(Pc*)n][Sm(Pc*)]} (n = 0–3) elucidate successive π–π interaction-linked extension in the perpendicular direction of the phthalocyanine plane along with increasing the stacked tetrapyrrole number, significantly improving the nonlinear optical properties including
三层四层、五层和六层夹层型化合物的电化学和理论研究[(Pc*)Sm][(Pc*)Cd n (Pc*) n ][Sm(Pc*)]} ( n = 0-3) 阐明了在酞菁平面垂直方向上的连续 π-π 相互作用连接延伸,同时增加了堆叠的四吡咯数,显着改善了非线性光学性质,包括有效的假想三阶分子超极化率和光学极限阈值。
