    Efficient methods for the synthesis of dibenzophenanthroheptaphene (DBPH) and tetrabenzotriphenylenopyranthrene (TBTP) were developed. As a result, a series of unprecedented derivatives of DBPH (1a–c) and TBTP (2a–b) were conventionally obtained from the Scholl cyclodehydrogenation reaction of their respective tribenzopentaphene synthons. An alternative convergent synthesis of DBPH is also...

    Tribenzopentaphene derivatives with lateral aromatic groups: the effect of the nature and position of substituents on emission properties

    Alameddine, Bassam ; Anju, Rajamohanan Sobhana ; Al-Sagheer, Fakhreia ; Jenny, Titus A.

    In: New Journal of Chemistry, 2016, vol. 40, no. 12, p. 10363–10370

    Nine new derivatives of the trapezoidal tribenzopentaphene (TBP) polycyclic aromatic hydrocarbon (PAH) were synthesized via the Suzuki–Miyaura palladium catalyzed cross-coupling reaction. The novel TBP derivatives, which bear various rigid and flexible aromatic groups either at their more accessible (R1) or congested (R2) bases, were fully characterized using high resolution mass...
