“…12 The synthetic manipulation of red phosphors can be readily achieved by altering the organic linker(s). 13,14 First, the organic linker itself can act as an antenna, and because Eu( iii ) has a low-lying, first excited state of 5 D 0 at 17 000 cm −1 , any organic linker with triplet state energy higher than 19 000 cm −1 can sensitize the Eu( iii ) centre efficiently and promote its emission quantum yields according to Latva ’ s empirical rule. 15 Second, attachment of various functional groups such as hydroxyl, amino or nitro groups can alter the nature of the steric effects through variable hydrogen bonds (HBs) in the crystal lattice.…”

“…Mechanochromic photoluminescent silicone materials with 1,1,2,3,4,5-pentaphenyl-1hydro-silol and other organic phosphors were reported in [93]. Coordination compounds of rare earth metals can also act as luminescent fillers [94][95][96][97]. Therefore, silicone materials with a PL quantum efficiency of 33% were obtained by [Eu(tta) 3 (H 2 O) 2 ] incorporation during the cross-linking via hydrosilylation reaction between tetramethyl-tetravinylcyclotetrasiloxane (D4Vi) and tetramethyl-tetrahydro-cyclotetrasiloxane (D4H) [95].…”

Polysiloxanes and materials based on them (silicone materials) are of great interest in optoelectronics due to their high flexibility, good film-forming ability, and optical transparency. According to the literature, polysiloxanes are suggested to be very promising in the field of optoelectronics and could be employed in the composition of liquid crystal devices, computer memory drives organic light emitting diodes (OLED), and organic photovoltaic devices, including dye synthesized solar cells (DSSC). Polysiloxanes are also a promising material for novel optoectronic devices, such as LEDs based on arrays of III–V nanowires (NWs). In this review, we analyze the currently existing types of silicone materials and their main properties, which are used in optoelectronic device development.

“…Thus, linear polysiloxanes, hyperbranched organosilicones, and polyhedral oligomeric silsesquioxane (POSS) derivatives could be utilized for the preparation of unconventional fluorescent materials [36]. Luminescent polysiloxanes can possess self-healing properties [37][38][39] can be applied in photonics [40,41] and as sensing devices for detecting nitroaromatic compounds [42] or oxygen [43,44]. Luminescent complexes could be introduced into a polysiloxane matrix as catalysts for a hydrosilylation-based cross-linking reaction, thereby playing two roles [45,46].…”

Nowadays, luminescent materials attract wide attention due to their valuable characteristics and broad area of potential application. Luminescent silicone-based polymers possess unique properties, such as flexibility, hydrophobicity, thermal and chemical stabilities, etc., which allow them to be utilized in various fields, such as optoelectronics, solid-state lasers, luminescent solar concentrators, sensors, and others. In the present work, a metal-ligand interaction approach was applied to obtain new cross-linked luminescent polymers based on multiligand polysiloxanes with grafted β-diketone fragments and organoeuropiumsiloxanes containing various organic substituents. Organoeuropiumsiloxanes were utilized as a source of Eu3+ ions due to their compatibility with the silicon matrix. All synthesized polymers were fully characterized and their physicochemical, mechanical, self-healing, optical, and thermal properties were studied.
