A new series of nonplanar and unsymmetrically β-functionalized "push-pull" copper corroles, CuTPC(CHO)R7 [R = H, Br, Ph, Me, or 2-thienyl (Th)], were synthesized characterized to elucidate the effect β-functionalization nonplanarity on photophysical, redox, nonlinear optical (NLO) properties corrole ring. The synthetic route β-octasubstituted corroles includes bromination CuTPC(CHO) get CuTPC(CHO)Br7 in 80% yield, which was further subjected Pd-catalyzed Suzuki reaction. exhibited a large red shift Soret band (Δλmax 35-40 nm) both Q bands 10-50 nm), as compared CuTPC CuTPC(CHO). 510 290 mV anodically shifted first oxidation reduction owing strong -I CHO Br groups. Density functional theory studies revealed that all highly saddle-shape conformation Very high torsional saddling observed for CuTPC(CHO)Th7 (79-83°) than (49-53°), even larger CuTPCBr8 (67-70°). Femtosecond laser-induced third-order NLO from these showed two-photon absorption cross-sections (0.48-6.98 × 104 GM) self-focusing-type positive refraction behavior. structure-dependent coefficients (β) are range ∼2.7-20.9 10-12 m/W, n2 values ∼0.64-6.45 10-18 m2/W. present results may facilitate window devices, femtosecond limiters, many other ultrafast photonic applications.

Symmetrically Functionalized Copper and Silver Corrole‐Bis‐Tetracyanobutadiene Push‐Pull Conjugates: Efficient Population of Triplet States via Charge Transfer

Chemistry - A European Journal, Journal Year: 2023, Volume and Issue: 29(41)

Published: May 3, 2023

Copper and silver tritolylcorroles (TTC) are symmetrically functionalized to carry two tetracyanobutadiene (TCBD) entities via [2+2] cycloaddition-retroeletrocyclization reaction involving ethynyl corroles with an electron acceptor, tetracyanoethylene (TCNE) in excellent yields, as the first examples of corrole-TCBD push-pull systems. The strong effect resulted charge polarization ground state resulting a considerable hypsochromic shift spectrum extending it into near-IR region. Electrochemical studies coupled computational revealed interactions between TCBD corrole π-system degree such was found depend on metal ion present cavity. Energy considerations suggested transfer (CT) from S2 or vibrationally hot S1 but not relaxed case CuTTC(TCBD)2 while CT occur all these states AgTTC(TCBD)2 . Additionally, high-energy populate low-lying triplet states. Systematic femtosecond pump-probe provided ultimate proof for occurrence excited function excitation wavelength followed by efficient population study brings out significance efficiently populating rather unusual copper carrying entities.
