β‑to‑β\nSingly Linked Subphthalocyanine\nDimers with Effective π‑Conjugation

In this work, a series of π-conjugated Subphthalocyanine\ndimers assembled by simple π-bridges were efficiently synthesized\nthrough metal-catalyzed reactions. Despite being singly linked, these\nreadily accessible arrays exhibit excellent π-electron communication,\nsignificantly perturbing the orbital distribution of conventional\nSubPcs and inducing notable alterations in their optical properties.\nThe findings presented here demonstrate the potential of SubPcs for\nconstructing curved porphyrin arrays with well-conjugated skeletons\nand intriguing functionalities.
