A method for the direct thermal patterning of a thermally labile 
-conjugated polymer film containinga NIR sensitive dye using a continuous wave 830 nm NIR diode laser is described. The method isdemonstrated with poly(3-(2-(2-tetrahydropyranyloxy)ethyl)thiophene) (PTHPET), which is renderedinsoluble upon localized heating with the NIR irradiation due to catalytically enhanced elimination andvolatilization of dihydropyran. The optical and photophysical properties of the patterned -conjugatedmaterial are described. High-resolution pixels (10 
m) of conjugated polymer can be obtained with laserdosages as low as 600 mJ/cm2 at laser scan speeds of 0.6 m/s. The method is capable of imaging largesurface areas, up to 1 m2, at relatively high throughput and with micrometer size resolution, and thuscould find application where the patterning of electroluminescent and/or conducting organic materialsare required.
