TY - JOUR AU - Schmidt, Maximilian; Hermann, Mathias; Otteny, Fabian; Esser, Birgit TI - Calix[n]phenothiazines: Optoelectronic and Structural Properties and Host–Guest Chemistry SN - 2625-1825 PY - 2020 JF - Organic Materials LA - EN VL - 02 IS - 03 SP - 235 EP - 239 DA - 2020/09/28 KW - Calixarenes KW - macrocycles KW - phenothiazine KW - host–guest chemistry KW - conformational flexibility AB - Calixarenes are of interest as receptors for ions and small molecules and as organic materials. Exchanging the arene units through heteroaromatics allows changing their optoelectronic and host–guest properties. We herein present calix[n]phenothiazines (n = 3, 4) as novel macrocycles, accessible in two-step syntheses. The phenothiazine units show reversible redox events and emissive properties, and N-hexyl-substituted calix[3]phenothiazine binds to both ammonium ions and a bisimidazole as neutral guests.
