BODIPY based hyperbranched conjugated polymers for detecting organic vapors

Abstract

BODIPY-based hyperbranched polymer showed improved selectivity and sensitivity for toluene as originated from the strong π–π interaction and high porosity within polymer matrix.

Surfactant modulated structural modification of hybrid poly(p-phenylenediamine)/titanium dioxide composites and investigation of their functional behaviour

“…In recent years, the polymeric materials have been gaining popularity in the field of organic electronics as organic conductive materials, because of their good environmental stability [6], possibility of tuning its conductivity by doping with suitable dopants [7] and relatively better gas separation efficiencies [8]. Furthermore, the polymers exhibit wide scope of applications in various fields, for example, in rechargeable batteries [9], electrochromic displays [10], electro catalysts [11], antistatic and anticorrosive materials [12], electrode materials [13], sensors [14], detectors [15] and gas separation membranes [16]. Transition metal oxide like TiO 2 possesses interesting characteristics like cost economic, nontoxic nature, ease of handling and resistance towards photochemical and chemical erosion [17].…”

Hyperbranched conjugated polymers containing 1,3-butadiene units: metal-free catalyzed synthesis and selective chemosensors for Fe3+ ions

“…16,17 Various transitionmetal-catalyzed polymerization methods have been used for the synthesis of hyperbranched conjugated polymers, such as Suzuki coupling polymerization, [18][19][20] click polymerization, 21,22 and Sonogashira coupling polymerization. 23,24 These well-established polymerization routes have played an indispensable role in the synthesis of hyperbranched conjugated polymers. However, these methods have drawbacks, such as harsh reaction conditions, tedious synthetic steps, the use of environmentally harmful transition-metal catalysts and solvents.…”

N-Benzoyl dithieno[3,2-b:2′,3′-d]pyrrole-based hyperbranched polymers by direct arylation polymerization

“…The Suzuki polymerization was also used to one-pot synthesize a hyperbranched conjugated polymer bearing dimethylamino groups to be used as a PSC cathode interlayer [ 24 ]. Sen et al [ 25 ] synthesized hyperbranched conjugated polymers based on 4,4′‐difluoro‐4‐bora‐3a,4a‐diaza‐ s ‐indacene (BODIPY) via Sonogashira cross coupling polymerization reactions. The polymers showed red shifts in absorption and emission maxima upon contact with toluene and benzene vapors.…”
