Luminescent reporter compounds that are rotaxanes having the structure
where B—Z—C is a reporter molecule based on a cyanine, squaric acid, or other reporter, and K is a macrocycle that encircles and interlocks with the reporter molecule. Applications of the reporter compounds are provided, as well as reactive intermediates used to synthesize the reporter compounds, and methods of synthesizing the reporter compounds.

several different squaraines are found to give spectrally blue-shifted aggregates in aqueous and mixed aqueous-organic solution and in microheterogeneous media (bilayer vesicles). While in some cases an intermediate dimer can be detected in the monomer to aggregate conversion process, in others direct conversion of monomer to aggregate is observed. The aggregation number can be determined together with
Two new 5,15-diarylporphyrin derivatives (L1 and L2) were designed and synthesized and their anti-esophageal cancer effects as photosensitizers were evaluated. Both compounds have strong absorption band at 645 – 655 nm in UV-Vis spectra, obvious singlet oxygen generation ability, and fluorescence emission around 657 – 674 nm under laser excitation. Under photodynamic therapy (PDT) conditions, they could significantly inhibit the growth of Eca-109 tumor cells. In particular, compound L1 exhibited excellent photodynamic antiproliferative effect and is worthy of further development.
