  1. 1. Ink Jetting of Photochromic Ink : Towards the Design of a Smart Textile Sensor

    Författare :Sina Seipel; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; UV curing; photochromic; UV-sensing; smart textile; resource-efficient; scCO2 dyeing; jetting; dye kinetics; color performance; durability; stabilization; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : Smart textiles have been a hot topic in research for several decades; however, comparatively few products can be found on the market. Resource-efficient processes can boost the breakthrough of smart and functional textiles, which often necessitate high-cost materials and only require small batches. LÄS MER

  3. 2. Controlling the Fluorescence Properties of Diarylethene-based Photochromic Systems

    Författare :Gaowa Naren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; isomerization; color change; photochromic molecules; molecular logic; intensity modulation; diarylethene; RGB; all-photonic; FRET;

    Sammanfattning : Diarylethene (DAE) photoswitches are one of the most promising families of photochromic molecules because of their outstanding photophysical/photochemical properties. This class of compounds, which can photoisomerize between an open colorless and a closed colored form, has been applied in various fields in this thesis work, spanning one-color fluorescence intensity modulation, all-photonic full-color reproduction, light-induced color changes for molecular logic gates and information processing.

  4. 3. Charge transport modulation in organic electronic diodes

    Författare :Fredrik Lars Emil Jakobsson; Magnus Berggren; Xavier Crispin; Paul W. M. Blom; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; switch device; memory; photochromic; trapping; resistance switching; Physics; Fysik;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER

  5. 4. Charge Transport Modulation and Optical Absorption Switching in Organic Electronic Devices

    Författare :Peter Andersson; Magnus Berggren; Ronald Österbacka; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; photochromic; PEDOT:PSS; active matrix display; switchable charge traps; printed electronics; switchable polarizer; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Organic electronics has evolved into a well-established research field thanks to major progresses in material sciences during recent decades. More attention was paid to this research field when “the discovery and development of conductive polymers” was awarded the Nobel Prize in Chemistry in 2000. LÄS MER

  7. 5. Mimicking the Binary World: Photochromic Compounds in Molecular Logic

    Författare :Martin Hammarson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA; dithienylethene; molecular logic; spiropyran; photochromism; porphyrin;

    Sammanfattning : The language of the binary world is used in, e.g., electronic circuits of a computer where a signal either can be on, known as 1 or off, known as 0. In the effort to make things smaller, molecules that mimic this binary world have been suggested as potential replacements for electronic circuits. LÄS MER
