Carbon fibre and Nano/micro (carbon nanotubes on carbon fibre) hybrid structures and their interface in advanced composites

In this chapter, we will briefly introduce in the first part some basic knowledge about CF properties, structure and fabrication process, as well as their application in composites. Then, we will present the modification of CF surface, and their…

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…
