摘要

Diphenylcarbinol single crystals were grown by cost-effective temperature-controlled solution growth technique of size 26 × 2 × 1 mm3. SCXRD and PXRD determined its orthorhombic crystal system and its structural parameters, which are a = 18.6499Å, b = 20.8936Å, c = 5.0359Å, and volume 1962.31 Å3. Molecular interactions and fingerprint plot of diphenylcarbinol (DPC) crystal were studied by Hirshfeld surface analysis and resulted that H–H intermolecular interaction dominates with 61.2% over other interactions. UV–Vis analysis revealed the linear optical response, direct allowed transition nature, and wide band gap 4.60 eV of the crystal. Thermal studies revealed high crystallinity, melting point 69 °C, and decomposition point 183 °C of the crystal. Diphenylcarbinol single crystal falls under the category of soft materials, which was revealed through microhardness study with work hardening coefficient 2.5. Voids cover 9.11% volume of the unit cell of DPC. High dielectric constant and low dielectric loss of organic DPC crystal are useful for good non-linear response. SHG study revealed the non-linear property of DPC, and its SHG efficiency is 30% of KDP. The promising results of diphenylcarbinol crystal under various characterizations suggest its potential to be used in electrical and non-linear applications.
