Anisotropic Metallosupramolecular Crystals for Autonomous Energy Transduction
Abstract
Manifestation of a flexible and environmentally compatible multifunctional energy harvester (MEH) is achieved through the use of a noncentrosymmetric metallosupramolecular crystal (MSC). Here, we report the design and synthesis of non-covalent interactions-mediated synthetic strategy of a MSC system using Cu(II) salt, allylmalonic acid, and 2,2ʹdipyridylamine system. Single-crystal X-ray diffraction and Hirshfeld surface analysis reveal a distorted square pyramidal geometry organized into an oscillatory 1D hydrogen-bonded chain, which ultimately perform the acentric polar nature of MSC crystals. This unique structural anisotropy enables high-efficiency multimodal energy harvesting. A flexible MEH was fabricated by employing MSC-system for the exploration of autonomous energy transduction. The MEH demonstrates superior piezoelectric performance, yielding a peak-to-peak short-circuit current (ISC) of ~ 1.2 µA and an opencircuit voltage (VOC) exceeding ~3.6 V under periodic mechanical excitation. The device exhibits a remarkable dual-sensitivity profile in low-pressure regimes and a peak power density of ~0.15 µW/cm
