THE MODIFICATION OF ELECTROCHEMICAL AND PHOTOELECTROCHEMICAL PROPERTIES IN THIN FILMS OF TRI- AND TETRAVALENT METAL PHTHALOCYANINES
Four different trivalent and tetravalent metal phthalocyanine systems (chlorogallium, chloroindium, vanadyl, and titanyl phthalocyanines) were used singly to prepare thin films (0.05-2.0 micron thickness) on gold, optically transparent substrates. The photoelectronic properties of these electrodes …

The Electronic and Vibrational Spectroscopy of Metal Phthalocyanines and Metal Phthalocyanine Chlorides Isolated in Low Temperature Solids
Phthalocyanines (Pcs) are an important class of dye molecules, capable of incorporating a wide range of metal atoms into their macrocyclic cavity and can be heavily substituted on their outer carbons. These highly stable molecules play an important role not only in the commercial dye industry, but …

The spectral and photophysical characterization of water solubilizing metal phthalocyanines for highly sensitive detection in biological studies
… Strategies are reported that produce symmetrical metal-free and metallo-phthalocyanine dyes, Pc and MPc, respectively, that contain various numbers of water solubilizing carboxylic acid groups on their periphery that provide a dual role by also serving as functional groups to covalently link …

Spin and Charge Dynamics in Organic Semiconductors
… to investigate lateral spin transport (LST) in metal phthalocyanines with the underlying theory explained in chapter 3. We present the full process of obtaining and characterising spintronics appropriate metal phthalocyanines and present the first ever room-temperature LST measurements on metal …

Terahertz Time-Domain Spectroscopy of Low-Dimensional Materials and Photonic Structures
… properties of graphite. </p><p>In Chapter 4 metal phthalocyanines have been investigated by the optical pump/THz probe technique. Disc-like phthalocyanine molecules self-assemble into columns and form quasi-1D conduction channels for efficient charge transport. With appropriate side groups …

Nucleation and growth of unsubstituted metal phthalocyanine films from solution on planar substrates
… to conventional solar cells. Unsubstituted Metal-phthalocyanines (Pc) are excellent electron donating molecules for heterojunction OSC. Usually organic solar cells with Pcs are produced by vapor deposition, although solution based deposition (like spin casting) is cheaper and offers more …

Organic/carbon nanotubes hybrid thin films for chemical detection.
Metallophthalocyanines (MPcs) are classified as an important class of conjugated materials and they possess several advantages attributed to their unique chemical structure. Carbon nanotubes (CNT), on the other hand, are known to enhance the properties of nano-composites in the conjugated …

Μελέτη διεπιφανειών λεπτών υμενίων φθαλοκυανινών με ανόργανα και οργανικά υποστρώματα με τη χρήση φασματοσκοπιών φωτοηλεκτρονίων
… ήδη στην αγορά. Η οικογένεια των φθαλοκυανινών (Phthalocyanines, Pcs) ανήκει στα οργανικά υλικά που ανταγωνίζονται επάξια τους ανόργανους ημιαγωγούς στις εφαρμογές σε ηλεκτρονικές διατάξεις όπως φωτοεκπομπές δίοδοι (LEDs), τρανζίστορ επίδρασης πεδίου (FETs), φωτοβολταϊκά στοιχεία (PVs), ηλιακά …
