Dinaphthoporphycenes: Synthesis and Nonlinear Optical Studies
摘要:
Naphthobipyrrole-derived porphycenes are synthesized for the first time via McMurry coupling of the beta-alkylated 2,9-diformylnaphthobipyrrole derivatives, which in turn were prepared easily from 2,3-naphthalene bishydrazine in four steps. Insertion of nickel into the porphycene core results in transformation of the rectangular N4-core into a square type geometry owing to the fusion of naphthalene moiety onto the bipyrrole entities. These porphycenes show large, intensity dependent three-photon absorption.

Naphthobipyrrole is a potentially useful building block for porphyrin and porphyrin analogue synthesis. Reported here is a simple, generalizable synthetic route to α-formylated, β-substituted naphthobipyrroles and their use in the preparation of binaphthoporphycenes. The resulting binaphthoporphycenes possess a planar geometry as determined via a single-crystal X-ray diffraction analysis; they also
Naphthobipyrrole 是卟啉和卟啉类似物合成的潜在有用构件。这里报道了一种简单、可推广的 α-甲酰化、β-取代萘并联吡咯的合成路线及其在制备双萘并卟啉中的用途。通过单晶 X 射线衍射分析确定,所得的双萘卟啉具有平面几何形状;与简单的卟啉相比,它们还显示出吸收最大值发生红移。
