Abstract:
The fluorescence behavior of porphyrins and phthalocyanines allows one to discriminate between monomeric and associated states of the dyes. These criteria are necessary prerequisites to decide about the inclusion behaviour of the dyes in oligomeric cyclodextrins. Masking the hydrophobic portion of the dyes by cyclodextrins allows one to transport these substances as inert through the body of an animal. The story is depicted here of how to proceed from functionalized porphyrinoids to tumor therapeutic drugs.

Abstract:
Xanthene dyes can be appended to cyclodextrins via an ester or amide bridge in order to switch the fluorescence on or off. This is made possible through the formation of nonfluorescent lactones or lactams as the fluorophore can reversibly cyclize. In this context we report a green approach for the synthesis of switchable xanthene-dye-appended cyclodextrins based on the coupling agent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM). By using 6-monoamino-β-cyclodextrin and commercially available inexpensive dyes, we prepared rhodamine- and fluorescein-appended cyclode

Abstract:
Cyclodextrins, derived from starch, are introduced as promising adsorbents capable of sequestering various pollutants, including heavy metals and dyes, although their solubility in water poses challenges for their removal after use. In this paper a bibliometric analysis is conducted using the Scopus database, yielding 649 relevant documents. Analysis indicates that the use of cyclodextrins in wastewater treatment is still in the early stages of growth and maturity, with most studies focusing on their application as adsorbents for dyes and heavy metals. However, the influence of other wastewate

Abstract:
Fluorescence spectroscopy and microscopy in biomolecular environments are usually performed in aqueous solution and preferably using red-emitting dyes. However, water quenches their fluorescence. We explore in this contribution how host-guest interactions between red-emitting fluorophores and macrocycles such as cyclodextrins and cucurbiturils can prevent quenching by shielding the dyes from water, thereby enhancing their brightness. We successfully apply this strategy in super-resolution imaging.

Abstract:
Supramolecular chemistry covers intermolecular interactions where non-covalent bonds are involved, and many of them are based on host-guest interactions. Cyclodextrins (CDs) are cyclic oligosaccharides consisting of 6-, 7- or 8-glucose units, which are called alpha-, beta- or gamma-CDs, respectively. They have hydrophobic interior and hydrophilic exterior, and are widely being used as hosts for various organic molecules. The formation of CD inclusion complexes with a variety of dyes has continuously drawn our interests, since CDs are readily available and have ability to include dye molecules

Abstract:
Cyclodextrins possess a hydrophobic cavity due to which they are suitable for inclusion of various organic dyes. The complex formation between CDs and dyes has been employed to affect the photophysical and photochemical characteristics of organic dyes such as fluorescence enhancement, charge and proton transfer, energy transfer, photochromic transformations and intramolecular excimer/exciplex formation. This fundamental approach has also potential nanotechnological application in creation of optoelectronic devices. Thus, the fluorescent hybrid nanomaterials consisting of supramolecular assembl
