[0053] Structure VII below shows yet another embodiment of the preferred chemical structure of the DVBDO that can be used in the present invention:
[0054]
[0055] When DVBDO is prepared by methods known in the art, it is possible to obtain one of three possible isomers: ortho, meta, and para. Accordingly, the present invention includes DVBDOs illustrated by any one of the above structures individually or as a mixture thereof. Structures VI and VII above show the meta (1,3-DVBDO) and para (1,4-DVBDO) isomers of DVBDO, respectively. The ortho isomer is rare; DVBDO is generally produced in most cases in a ratio of meta (structure VI) to para (structure VII) isomers in the range of 9:1 to 1:9. As an embodiment, the present invention preferably includes a ratio of structure VI to structure VII in the range of 6:1 to 1:6, and in other embodiments, the ratio of structure VI to structure VII may be in the range of 4:1 to 1:4 or 2:1 to 1:2 range.

Embodiment 1
[0132] In this Example 1, COTE was produced by first preparing a curable formulation as follows:
[0133] A liquid carbon precursor solution containing DVBDO / p-cresol / MPTS was prepared by adding the three components of the formulation at ambient temperature using a weight ratio of 87 / 12 / 1. The liquid formulation was tumble mixed for 15 minutes. The formulation is then diluted in a good solvent such as tetrahydrofuran, acetone or mixtures thereof. In order to obtain different thicknesses, the concentration of the liquid carbon formulation in the solvent formulation is 1 to 50%.
[0134] The viscosity of the formulation is 12 mPa-s.
[0135] Quartz substrates (typically 7 cm x 7 cm) were cleaned with acetone and isopropanol, then dried with nitrogen and subjected to oxygen plasma treatment using a Harrick plasma cleaner PDC-001.
[0136] The solution was filtered through a 0.2 μm filter and spin-coated on a quartz slide substrate at an angular velocity between 1000 rpm and 60...
Embodiment 2
[0141] In this Example 2, COTE was produced by first preparing a curable formulation as follows: a liquid carbon precursor solution containing the following three components: DVBDO / p-cresol / MPTS by using the corresponding 87 / 12 / A weight ratio of 1 was prepared by mixing the three ingredients of the formulation. The liquid formulation was tumble mixed for 15 minutes.
[0142]Quartz substrates (glass slides) (typically 7 cm x 7 cm) were cleaned with acetone and isopropanol, then dried with nitrogen and subjected to oxygen plasma treatment using a Harrick plasma cleaner PDC-001.
[0143] The solution was filtered through a 0.2 μm filter and heated until it reached 55°C to reduce its viscosity and spin-coated on a 60°C preheated glass slide for 45 seconds (s) at an angular velocity between 1,000 rpm and 6,000 rpm.
[0144] The coated glass slides were baked at 150 °C for 60 s. The baked samples were then annealed in a vacuum tube furnace under a nitrogen inert atmosphere. Unde...
