“…Metachromic cationic dye methylene blue was investigated for organization in the LbL framework [26]. In addition, photocleavable chromophores [27], laser absorbing dye (IR-806) [28], bacteriorhodopsin [29], phthalocyanine [30], porphyrin [31,32], and naphthalocyanine [33] have been also incorporated in microcapsules for remote opening by laser light, but it was also noticed that inorganic nanoparticles appeared to be much more effective laser light absorbers…”

Originally regarded as auxiliary additives, nanoparticles have become important constituents of polyelectrolyte multilayers. They represent the key components to enhance mechanical properties, enable activation by laser light or ultrasound, construct anisotropic and multicompartment structures, and facilitate the development of novel sensors and movable particles. Here, we discuss an increasingly important role of inorganic nanoparticles in the layer-by-layer assembly—effectively leading to the construction of the so-called hybrid coatings. The principles of assembly are discussed together with the properties of nanoparticles and layer-by-layer polymeric assembly essential in building hybrid coatings. Applications and emerging trends in development of such novel materials are also identified.

“…As a consequence of their high tendency to form aggregates, a drop of fluorescence and singlet oxygen quantum yields is observed [ 30 , 31 ]. There have been several structural variations introduced to overcome the solubility and aggregation issues of (na)phthalocyanines, including the insertion of bulky substituents in the peripheral positions of the macrocycles [ 25 , 32 , 33 , 34 , 35 ], the addition of axial ligands to the central atom [ 28 , 30 , 36 , 37 , 38 , 39 ], or the encapsulation of the dye in colloidal particles [ 40 , 41 ]. Furthermore, peripheral functional groups in Ncs macrocycles may be utilized to further tailor intra- and intermolecular interactions as well as optical, photochemical, and electrochemical properties; particularly, aromatic groups increase intermolecular π - π interactions [ 19 , 34 ].…”

Metal phthalocyaninates and their higher homologues are recognized as deep-red luminophores emitting from their lowest excited singlet state. Herein, we report on the design, synthesis, and in-depth characterization of a new class of dual-emissive (visible and NIR) metal naphthalocyaninates. A 4-N,N-dimethylaminophen-4-yl-substituted naphthalocyaninato zinc(II) complex (Zn-NMe2Nc) and the derived water-soluble coordination compound (Zn-NMe3Nc) exhibit a near-infrared fluorescence from the lowest ligand-centered state, along with a unique push–pull-supported luminescence in the visible region of the electromagnetic spectrum. An unprecedentedly broad structural (2D-NMR spectroscopy and mass spectrometry) as well as photophysical characterization (steady-state state and time-resolved photoluminescence spectroscopy) is presented. The unique dual emission was assigned to two independent sets of singlet states related to the intrinsic Q-band of the macrocycle and to the push–pull substituents in the molecular periphery, respectively, as predicted by TD-DFT calculations. In general, the elusive chemical aspects of these macrocyclic compounds are addressed, involving both reaction conditions, thorough purification, and in-depth characterization. Besides the fundamental aspects that are investigated herein, the photoacoustic properties were exemplarily examined using phantom gels to assess their tomographic imaging capabilities. Finally, the robust luminescence in the visible range arising from the push–pull character of the peripheral moieties demonstrated a notable independence from aggregation and was exemplarily implemented for optical imaging (FLIM) through time-resolved multiphoton micro(spectro)scopy.
