Synthesis, characterization, morphological behaviour, and photo-and electroluminescence of highly blue-emitting fluorene-carbazole copolymers with alkyl side-chains of different lengths

Four novel phenyl-end-capped π-conjugated polymers comprising alkyl chains of different lengths were synthesized: the poly(9,9-dihexyl-2,7-fluorene-alt-9,9-dioctylfluorene) (P0), the alternating fluorene-carbazole copolymers P1 and P2 comprising 20%…

Ultrabright Fluorescent Polymeric Nanoparticles Made from a New Family of BODIPY Monomers

Four novel BODIPY derivatives (π-) functionalized by different polymerizable groups, styrene (S), phenyl acrylate (PhA), ethyl methacrylate (EtMA) and ethyl acrylate (EtA) have been synthesized. Following a formerly established one-pot RAFT…

LumicyanoTM: A new fluorescent cyanoacrylate for a one-step luminescent latent fingermark development

Latent fingermarks developed by cyanoacrylate fuming often lack contrast; therefore further enhancement is required, such as dye staining. This second step is part of the conventional detection sequences performed by forensics practitioners. Dye…

Fluorescent Labelling of a Bis-Urea based Supramolecular Polymer

Bisurea-based supramolecular polymer EHUT (2-ethylhexyl-3-[3-(3-(2-ethylhexyl)ureido)-4-methyl-phenyl]urea) has been shown previously to self-assemble through hydrogen bonding into high-molecular-weight structures. The present publication reports…

Spectral, conformational and photochemical analyses of photochromic dithienylethene: <i>cis</i>-1,2-dicyano-1,2-bis(2,4,5-trimethyl-3-thienyl)ethene revisited

The conformational equilibrium and thermodynamic parameters of cis-1,2-dicyano-1,2-bis(2,4,5-trimethyl-3-thienyl)ethene (1a) and its trans derivative 1c are presented. Irradiation of both compounds was carried out by using 365 nm light, which…

Linear and nonlinear optical properties of tris-cyclometalated phenylpyridine Ir(III) complexes incorporating π-conjugated substituents.

The synthesis, luminescence, and nonlinear optical properties of a new series of Ir(ppy)3 (ppy = 2-phenylpyridine) complexes incorporating π-extended vinyl-aryl substituents at the para positions of their pyridine rings are reported. Appropriate…
