The organic crystals of Tröger's base (TB) analogues with ortho-/meta-substituted terminal pyridine units, 2,8-(6H,12H-5,11-methanodibenzo[b,f]diazocineylene)-di(o-ethenylpyridine) (TBOP) and 2,8-(6H,12H-5,11-methanodibenzo[b,f] diazocineylene)-di(m-ethenylpyridine) (TBMP), were prepared using solvothermal method. By alternating the solution system and...
