Study on new quinacridone derivatives with enhanced third-order nonlinear optical properties

Seven new quinacridone derivatives were designed and synthesized. The relationship between molecular structure and nonlinear optical properties was studied by cyclic voltammetry, DFT calculation and Z-scan. By introducing strong electron donating groups at the two sides of the quinacridone, and then introducing a strong electron withdrawing group dicyanoethylene group, the band gap of the molecule can be effectively reduced, and the intramolecular charge transfer can be promoted. The results shown that the HOMO/LUMO band gaps of the target compounds are all reduced, and QA-F has the best third-order nonlinear optical performance, and its γ (γ = 5.32 × 10?33 esu) is 4.38 times that of QA-1 (γ = 1.21 × 10?33 esu).

2,2,2-trifluoroacetophenone-based D-π-A type photoinitiators for radical and cationic photopolymerizations under near-UV and visible LEDs

Two D-π-A-type 2,2,2-trifluoroacetophenone derivatives, namely, 4′-(4-(N,N-diphenyl)amino-phenyl)-phenyl-2,2,2-trifluoroacetophenone (PI-Ben) and 4′-(4-(7-(N,N-diphenylamino)-9,9-dimethyl-9H-fluoren-2-yl)-phenyl-2,2,2-trifluoroacetophenone (PI-Flu), are developed as high-performance photoinitiators combined with an amine or an iodonium salt for both the free-radical polymerization of acrylates and the cationic polymerization of epoxides and vinyl ether upon exposure to near-UV and visible light-emitting diodes (LEDs; e.g., 365, 385, 405, and 450 nm). The photochemical mechanisms are investigated by UV-Vis spectra, molecular-orbital calculations, fluorescence, cyclic voltammetry, photolysis, and electron-spin-resonance spin-trapping techniques. Compared with 2,2,2-trifluoroacetophenone, both photoinitiators exhibit larger redshift of the absorption spectra and higher molar-extinction coefficients. PI-Ben and PI-Flu themselves can produce free radicals to initiate the polymerization of acrylate without any added hydrogen donor. These novel D-π-A type trifluoroacetophenone-based photoinitiating systems exhibit good efficiencies (acrylate conversion = 48%-66%; epoxide conversion = 85%-95%; LEDs at 365-450 nm exposure) even in low-concentration initiators (0.5%, w/w) and very low curing light intensities (1-2 mW cm-2).

One/two-photon-sensitive photoacid generators based on benzene oligomer-containing D-π-A-type aryl dialkylsulfonium salts

Novel sulfonium-based D-π-A photoacid generators (PAGs) with a benzene oligomer (from one to four) as a π-conjugated system that are highly photosensitive in the near-ultraviolet region (365 nm) were prepared. The maximum absorption and molar extinction coefficients of the PAGs redshifted and enhanced with the increasing length of the conjugated systems. The quantum yields of PAGs were high (three of them were over 0.6) and improved by adjusting the number of the phenyl rings. The quantum chemical calculation results proved that the molecular configuration and nature of the frontier orbitals are crucial factors which affect PAG performance. Photopolymerization kinetic results demonstrated that these sulfonium-based PAGs were highly efficient cationic photoinitiators, and the i-line sensitivities were evaluated based on the photolithographic performance of the PAG-containing SU-8 resins. In addition, the two-photon absorption cross sections (δ700 nm > 400 GM) matched the requirements needed in the 3D fabrication of polymer microstructures.

Terphenyl backbone-based donor-π-acceptor dyads: Geometric isomer effects on intramolecular charge transfer

The molecular geometry effects of ortho, meta, and para-terphenyl based donor-π-acceptor (D-π-A) dyads on intramolecular charge transfer (ICT) were studied to investigate structure-ICT relationships. Terphenyl based D-π-A dyads were prepared by two-step palladium catalyzed, Suzuki-Miyaura coupling reactions, in which triphenylamine (TPA) was used as the electron donor and 1,2-diphenyl-benzimidazole (IMI) as the electron acceptor. The photophysical and electrochemical properties of terphenyl backbone-based ortho (O), meta (M), and para (P) dyads were compared. In steady state absorption spectra, a red-shift of CT band was observed in the order O M P, which was attributed to terphenyl isomer conjugation effects and agreed well with density functional theory (DFT) based calculations. In particular, the emission spectra of the three terphenyl D-π-A dyads produced showed similar emission maxima at ～475 nm and a bathochromic shift property was observed in order to increase the solvent polarity, indicating the ICT process. From Lippert-Mataga plots, excited-state dipole moment changes (Δμ) were estimated to be 31.5 Debye (D) for O, 62.9 D for M, and 51.5 D for P. For M isomer, a large Δμ and the markedly reduced quantum yield was shown, as well as photo-induced electron transfer (PET) was expected in the excited state, but no radical species were observed by femtosecond transient absorption (TA) measurements. Based on experimental results, we conclude that all three terphenyl based D-π-A dyads, including non-conjugated ortho- and meta-terphenyl dyads, exhibit partial charge transfer rather than unit-electron transfer.
