Novel bridged anthracene derivatives and polyesters and copolyesters therefrom

Abstract

Abstract9,10‐Bis(hydroxymethyl)triptycene, 9,10‐dihydro‐9,10‐bis(hydroxymethyl)‐9,10‐ethanoanthracene, 9,10‐dihydro‐9,10‐bis(hydroxymethyl)‐9,10‐(2,3‐bicyclo[2.2.1] heptano)‐anthracene, 9,10‐dihydro‐9,10‐bis(hydroxymethyl)‐N‐phenyl‐9,10‐ethanoanthracene‐11,12‐dicarboximide, and 9,10‐bis(carbethoxy)triptycene have been prepared and employed as modifying agents to improve the physical properties of polyesters such as poly(ethylene terephthalate). Especially noteworthy are the high glass transition temperatures (Tg) which can be obtained.

Synthesis and characterization of novel organosoluble and thermally stable polyamides bearing triptycene in their backbones

“…The chemistry of triptycene has been studied in comparative detail and has been summarized in an earlier review paper reported by the Russian researchers [22]. Perhaps the earliest efforts in the study of triptycene polymers were made at Eastman Kodak and DuPont in the late 1960s wherein bifunctional, bridgehead-substituted triptycenes were synthesized and used to prepare a series of triptycene polymers, including polyesters, polyamides, polyurethanes, and a polyoxadiazole [23,24]. However, the synthesis and properties of triptycene-containing polymers have only begun to attract attention since 1998 [25][26][27][28][29][30][31].…”

Triptycene poly(ether-imide)s with high solubility and optical transparency

“…Its rigid, three-dimensional framework has been incorporated in molecular rotors, [35,36] molecular cages, [37,38] and supramolecular architectures [39,40]. Perhaps the earliest efforts in the study of triptycene polymers were made at Eastman Kodak and DuPont in the late 1960s wherein bifunctional, bridgehead-substituted triptycenes were synthesized and used to prepare a series of triptycene polymers, including polyesters, polyamides, polyurethanes, and a polyoxadiazole [41,42]. However, the synthesis and properties of triptycenecontaining polymers have only begun to attract attention since 1998 [43][44][45][46][47][48][49].…”

Design and synthesis of triptycene based fluorescent polymer with pendent triazole: Effect of functionality on host–guest interaction

“…Derivatives of triptycene have been extensively used for the synthesis of variety of macromolecules and supramolecular functional materials . The polymer chemistry of triptycene was first reported in late 1960s wherein various polyamides, polyesters, and polyurethanes were synthesized from triptycene derivatives . After a gap of three decades, the syntheses of polymers containing triptycene motif was revived by Long and Swager in last decade of 20th century …”
