cis‐Linked cyclotetraphenylene dimer [2]c‐CTPE and trimer [3]c‐CTPE were synthesized via Pt‐mediated cyclization of cis‐diboronated tetraphenylethene. The structure of [2]c‐CTPE has been confirmed by single crystal X‐ray diffraction. The strain energy of [2]c‐CTPE and [3]c‐CTPE was calculated to be 86.28 ⋅ kJ mol−1 and 9.23 kJ ⋅ mol−1, respectively. [2]c‐CTPE and [3]c‐CTPE are typical AIEgens and show mechanofluorochromic properties. The comparisons of cis‐linked cyclotetraphenylenes with gem‐linked cyclotetraphenylenes were also discussed.

Conjugate addition of ethanol and subsequent oxidation with [bis (trifluoroacetoxy)iodo]benzene (PIFA) allowed for the inner ethoxylation of 3‐oxo‐N‐confused tetraphenylporphyrin (ONCP). First oxidation of ONCP with PIFA followed by treatment with ethanol gave two more N‐confused phlorins derivatives 5 and 6. [ABSTRACT FROM AUTHOR]
