Impact of the Acceptor Group on the Properties of Triphenylamine-Donor-Acceptor Dyes: An Experimental and Computational Study.
J Phys Chem A
January 2025
Department of Chemistry and Dodd Walls Centre, University of Otago, Dunedin 9016, New Zealand.
Three triphenylamine-Indane donor-acceptor dyes with different functional groups on the acceptor were studied to investigate how substitution would affect the optical properties. The dyes studied were IndCN, containing two malononitrile groups; InO, with two ketone groups; and InOCN, which features mixed functional groups. A combination of Raman spectroscopy, UV-vis absorption and emission spectroscopy, and density functional theory (DFT) calculations were employed for characterization.

Background: With the development of sequencing technology and the rapid increasing in the number of sequenced genomes, lineage-specific genes (LSGs) have been identified and characterized across various species. Similar to other conserved functional genes, LSGs play a crucial role in biological evolution and development. However, the understanding of LSGs remains limited.

Sjögren's syndrome-related dry eye (SSDE) is a severe dry eye subtype characterized by significant immune cell attacks on the lacrimal gland. However, delivering immunosuppressive drugs to the lacrimal glands for SSDE therapy safely and sustainably poses significant challenges in clinical practice. Herein, a ROS-responsive microneedle patch with detachable functionality (CE-MN) is developed to enable straightforward and minimally invasive administration to the lacrimal gland area by penetrating the periocular skin.

Selective therapeutic targeting of T-cell malignancies is difficult due to the shared lineage between healthy and malignant T cells. Current front-line chemotherapy for these cancers is largely nonspecific, resulting in frequent cases of relapsed/refractory disease. The development of targeting approaches for effectively treating T-cell leukemia and lymphoma thus remains a critical goal for the oncology field.

The challenge of healing diabetic skin wounds presents a significant hurdle in clinical practice and scientific research. In response to this pressing concern, we have developed a temperature-sensitive, in situ-forming hydrogel comprising poly(-isopropylacrylamide---butyl acrylate) -poly(ethylene glycol) -poly(-isopropylacrylamide--butyl acrylate) copolymer, denoted as PEP, in combination with zinc oxide nanoparticles, forming what we refer to as PEP-ZnO hydrogel. The antimicrobial properties of the PEP-ZnO hydrogel against methicillin-resistant were rigorously assessed by using the bacteriostatic banding method.
