Cyclophanes resorcinarenes

Cavitand A general term for a host structure that has an enforced cavity large enough to accommodate guest molecular entities. Examples include cyclodextrins, rigid cyclophanes, resorcinarenes, spherands, etc. 

Cyclophane-based resorcinarene trimer bearing a dansyl moiety and 28 carboxylate residues Fluorescent probes capable of sensing post-translational modifications of histone Exhibited potent discrimination capability between histone and chemically acetylated histone due to the electrostatic interactions [102]...

Fig. 4 Representatives of typical cyclophane host families calixarene (21), resorcinarene (22), cavitands (23, 24), cdrcerand (25). hemicarcerand (26), crown ether (27), cryptand (28), spherand (29). and hemispherand (30)...

Today, these macrocycles have opened access to promising supramolecular systems and are discussed in recent monographs on cyclophanes [8]. We prefer to call them resorcinarenes and not calixarenes for two reasons first, the name calixarenes...
